A motion assistance apparatus may include a shank frame configured to support a shank of a user, a thigh frame configured to rotate relative to the shank frame and support a thigh of the user, and a driving frame configured to assist a motion of a hip joint of the user by transmitting power directly or indirectly to the shank frame.

An elbow joint boost device has first and second frames to be attached to the forearm and lower arm of a patient. A guide mounted on the first frame extends generally along the respective one of the forearm and upper arm. A link is mounted on the guide for sliding movement along the guide, and a spring acts in tension between the sliding link and a point on the second frame remote from the patient's elbow. As the patient straightens and bends the elbow, the link can slide along the guide, varying the leverage of the tension spring.

A male masturbation device, includes a soft artificial colloid set in a housing which imitates the vagina, and a cavity is provided in the artificial colloid for accommodating the penis, a movement drive is provided along the housing and drives the artificial colloid to move along and stimulate the penis. The artificial colloid simulates the female vagina and when the movement drive drives the artificial colloid to move along the penis, it just likes a real sexual behavior. So that makes user experience a more realistic effect and better stimulate the male reproductive organs and achieve orgasm.

An articulated patient support platform cyclically expands and contracts a patient's lung volume, to both support breathing and mobilize lung tissue. In the lung expansion phase, a change in angle between a leg and hip supporting portion and a chest and head supporting portion causes extension the patient's spine, which increases the distance between the patient's sternum and spine. In the lung contraction phase, the reverse change in this angle causes flexion the patient's spine, which decreases the distance between the sternum and spine. A cycle of increase and decrease in spine-sternum distance expands and contracts lung volume in the manor of a bellows. Motorized operation of the platform thereby provides non-invasive natural breathing support. A corollary benefit of this lung expansion/contraction cycle is mobilization of lung tissue, which is beneficial in reducing post-operative pneumonia risk.

A telescopic impact sperm collector includes an outer cup body, a soft cup body, and an inner cup body, a transmission mechanism and a drive mechanism which are installed in the outer cup body. The soft cup body has a massage cavity with a front opening; both ends of the soft cup body are connected to a cup mouth of the outer cup body and the inner cup body respectively; the drive mechanism includes a brushless motor; the transmission mechanism includes a mandrel and a cam; the mandrel has an end hinged to a rear end of the inner cup body and the other end transmissively connected to the brushless motor through the cam; the inner cup body can be driven by the brushless motor to slide back and forth in the outer cup body.

A wearable device, includes a motor, a motor driver circuit, a memory, a sensor, and a processor. The memory is configured to store resistance force generation setting information indicating a difference between a reference angle and each joint angle and a corresponding relationship between respective duty ratios. The processor is configured to obtain, using the sensor, a joint angle of a user and calculate a difference between the reference angle and the obtained joint angle. The processor is configured to obtain a duty ratio corresponding to the calculated difference according to the resistance force generation setting information. The processor is further configured to provide a control signal having the obtained duty ratio to the motor driver circuit to perform control such that a control state of the motor driver circuit is switched between a first control state and a second control state.

A device for supporting a lower limb of a subject. The device has a housing for a lower limb and a limb support. The housing has a longitudinal axis aligned with a longitudinal axis of the lower limb. A driving mechanism connected between the housing and the limb support, causes movement of the limb support between a retracted position parallel to the longitudinal axis of the housing and an extended position in which the limb support extends perpendicularly to the longitudinal axis of the housing to support the lower limb.

The present invention relates to the field of family health care, in particular to a manual massager with grounding benefits. The highly portable and manual device transfers the user's body excess voltage and transfers through the wire to grounding port and thus deposited to Earth. The assembly incorporates the benefits of grounding (earthing) with the benefits of massage therapy. The manual massager has a simple structure, low manufacturing cost and controllable massaging force, and is convenient to use.

A supporting module including a supporting frame including a proximal end and a distal end, a connecting plate connected with the distal end of the supporting frame, a sliding plate in contact with one face of the connecting plate, a supporting band connected to both ends of the connecting plate, and an elastic strip configured to connect the sliding plate and the connecting plate is disclosed.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.
